xrightharpoondown
Draws a right-pointing harpoon with a downward-oriented barb above mathematical expressions.
Overview
Commonly employed in advanced mathematics and physics to denote specialized mappings or transformations with specific directional properties.
- Often used in category theory and abstract algebra to indicate particular types of morphisms.
- Appears in texts discussing vector fields and differential geometry.
- Useful for representing specialized mathematical operations where both direction and orientation are significant.
- Frequently combined with other arrow notations to create precise mathematical notation systems.
Examples
